WINDOW-LOCK.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application vfiled July 19, 1915, Serial No. 40,668. Renewed June 1,1916. Serial No. 101,158.

To all whom t may concern c Be it known that I, HENRY Gnonem'a citizenof the United States, and a resident of Brooklyn, in the county of Kingsandl closed position and thereby prevent the window from being opened,but also to draw the meeting rails of the two sashes forcibly togetherand thereby render the forcing of the lock, by means of atool from theoutside of the structure or apartment lin which the window is built,practically impossible.

The above and other objects and advantages of my invention will appearfrom the following' description, taken in connection with theaccompanying drawings; and be fully pointed out in the appended claims.I wish to have it understood, however,pthat the disclosure hereinisillustrative only, and

vcomprises lbut one embodiment of my ini-- 'proved construction; andthat the principle thereof may be practised by other constructions thatare similar in effect. Otherwise stated, differences in the phrasing ofthey claims are intended to cover differences in structural details thatI may find it advisable to adopt; provided such dierences lie within thescope and spiritvof my invention as the claims express the same.

On said drawings: Figure l is a front elevation of a portion of a pairof sashes making up a window, showing my improved lock in position. Fig.2 is a view for the most part in section, taken on the line 2-2 ofFig. 1. Fig. 3 is a similar sectional view showing a part of the lock onan enlarged scale and illustrating more fully, the interior constructionthereof; and, Fig. 4 is a perspective view of another portion of myimproved lock adapted to coperate with the parts shown in Fig. 3.

. In the particular description of the drawings the same numerals ofreference are used to indicate the same parts throughout `the severalviews. Y

I employ the numeral l to indicate the frame'of a window, and in saidframe are mounted to slide in vertical guideways, arranged side by sideeach other, -a lower sash 2 and an upper sash 3. These sashes arearranged to be secured together by means of my improved lock, the partsof which are mounted in the lower rail of the upper sash and the toprail of the lower.; and my lock comprises a rotatable rod 4, which iscarried by the sash 2 and which terminates at its inner end in alateralarm or finger 5. This arm or finger 5 is .adapted to engage witha thimble (i, fixed in the lower rail vof the sash 3, and having'aportion 7 which provides an inclined surface which the finger 5engages.` By causing the rod V4 to move into operative position withrespect to the capl or thimble 6, the sashes 2 and 3 are secured againstmovement in the guides of the frame l; and by turning this rod thelinger 5 engages with the portion 7, providing the inclined surfaceabove mentioned, in such a way as to draw the meeting rails of thesashes 2 and 3 together; whereby the space` between these rails ispractically closed, and the insertion of a tool between them so as toforce the lock effectually prevented.

The rotatableJ rod or bar 4 is housed in a tubular casing 8, which canconveniently be made out of a piece of pipe or tubing, and is adapted tobe placed in a bore or passage through the upper rail of the sash 2,made by a bit or auger. The end of thecasing 8 which is presented t0 theinside of the window. is made rigid with a perforated disk or collar 9,having openings through which screws or nails can be driven into thesash to secure the casing 8 in place. The casing and the disk arefastened tightly together, and for this purpose the adjacent end of thecasing is formed over to provide a lip 10, which engages the outer faceof the disk 9 snugly and closes the seam around the casing and betweenthe same and the disk. At its opposite end the casing S receives abearing 11, which may be a short piece of pipe or nipple of lessdiameter than the casing 8 and somewhat thicker, so as to provide forslidably mounting the end of the rod 4 carrying the finger 5, andthereby enable the rod to be conveniently4 reciprocated and turned whenthe lock is to be used.- The opposite end of the rod 4 -is surrounded bymeans of a bushing or sleeve 12, which may also be made of a short sec-Iii) tion of pipe or a nipple of thick tubing of such a diameter as toenable it to enter the end of the casing 8 and serve as a plunger; thisbushing fitting the bore of the casing snugly, but not too tightly toprevent either reciprocating or rotatory movement. Inside the casing andsurrounding the rod et is a spiral spring 18 abutting against thebearing 11 at one end and against the bushingV 12 at the other, andnormally acting to urge the rod l inward with respect to the apart--ment or building so as to keep the nger 5 in retracted ielation. Thebushing 12 is, of course, made rigid with the rod 4, and on the innerend of this rod is a handle 1.1 which terminates in a finger piece 15.rlhe handle 14 may be mounted on the rod by perforating the handle andriveting the end of the rod l thereto; and if desired 1 may form arosette on the handle ll4 around or over the riveted end of the rod 1for purpose of ornament.

The thimble or cap G is provided with a central opening 16 in the end 17thereof; this opening being long enough to receive the linger 5, and ofless width than the length of the same. The end 17 of the cap or thimble6 is not fiat or plane, but is provided with section 7, above mentioned,which af- A fords an inclined surface with which the finger 5 mayengage, and the end of this section is joined to the remaining or planepoi'- tion of the bottom 17 by a shoulder 18. This thimble is hollow asshown partly in F ig. 2;

and the cylindrical body thereof enables it to be readily inserted in arecess 2O in the lower railkof the sash 3. This recess 2O need not be asdeep as the distance between the terminal edge of the cylindricalsection 19 l and the end 17 of the thimble 6; so that after insertingthe thiinble 6 into the recess 20 as fai' as it will gowithout the useof tools, the thimble can` be driven in by means of a hammer or malletuntil its end 17 is flush with the side of the rail of the sash 3.

The utility of my invention will now be clear. lVith the parts in properpositions the two sashes will be free to move so long as the linger 5and the handle 111 are in the positions shown in Fig. 3; in such a casethe spring 13 will withdraw the finger 5 and keep it clear of thethiinble 6 so that either sash can be opened. Then it is desired tosecure the two sashes together, the bar 4 is first pushed inward, thefinger at this time extending vertically downward. It is therefore freeto move through the elongated openingV 16 and thus pass to the inside ofthe cap or thimble 6. The handle is then turned from the verticalpositionshown in Fig. 3 to horizontal position or farther than this; andthis rotation thro-ugh nearly half a circle will cause the finger 5tomove loe=y against the force of the spring 13. As a result, the twosashes will not only be held against vertical movement, but drawntogether horizontally so as to close the space between them. The end ofthe finger 5 may be beveled slightly to enable it to work more smoothlyagainst the inclined surface provided by the section 7, and the end ofthe thiinble or cap G will be provided with a suitable number of holesto receive nails or fastening screws.

Y l show in Fig. 2 the adjacent faces of the meeting rails of the sashes2 and Si Jeveled, but obviously my invention may be applied to sasheswhich have straight or vertical faces instead of the beveled faces, aswell as to sashes which are beveled, which have illustrated. .The lock"consists of relatively few parts, and it can be readily mounted uponalmost any window merely by boring holes in the sash rails of thesamediameters as the casing 8 and thimble 6 to receive these parts. Afterthe holes in question are once made it is the work of but a moment or soto put the casing 8 and thimble 6 in place and apply the fasteningdevices to hold them. rllhe lock is very easy to operate and makes avery neat and compact device. Then the handle 15 is moved down to causethe finger 5 to draw the rails of the sashes 2 and 3 toward each other,all space between the two sashes is practically closed up and it becomesimpossible to force the lock by means of a tool or other instrumentapplied between the sashes, and the window will be held in tightlyclosed position against any force short of that necessary to break thesash or the panes of glass carried by them.

Having described my invention, what I believe to be new, and desire tosecure and protect by Letters Patent of the United States is 1.. In alock for windows, the combination of a. short cap or thinible having oneend open, said end adapted to be inserted in a recess in the sash rail,said cap having its other end closed providing a bottom having anelongated opening therein, the bottom being Hat adjacent one side ofsaid opening and being shaped t'o have a cam surface on the otherside,the flat side of the bottom being joined to the inside by an abruptshoulder, and means adapted to be mounted in an adjacent sash to engagethe inclined portion of the bottom of said cap.

2. In a lock for windows the combination of a short cap or thiinblehaving one end open, said end adapted to be inserted in a recess in asash rail, said cap having its other end closed providing a bottom withan elongated opelling therein, the bottom being fiat adjacent one sideof said opening and shaped to have a cam surface on the otherrside, theflat side being joined to the inclined side by an abrupt shoulder, atubularcasing adapted to be mounted in a bore through the rail of anadjacent sash in line with Said cap, said casing having a perforatednipple in one end adjacent the cap providing a hearing, a bar in saidcasing having one end projecting through said bearing, and having afinger on said end to enter said opening in the bottom of the cap toengage the cam surface7 a sleeve or bushing mounted on Said bar at itsopposite end extending into the Copies of this patent may be obtainedfor ve cents each, by addressing the opposite end of the casing, acoiled spring 1n the casing surrounding the bar andengaging the sleeveand bearing to retract said linger, a handle secured to the bar adjacenti said bushing, a perforated disk receiving the end of the casing remotefrom the bearing, the said end of the casing being formed over toprovide a lip to engage the face of the disk and means for securing saiddisk to said adjacent sash rail.
